.WEATHE R-STRIP.

' SPECIFICATION forming part of Letters Patent No. 284,602, datedSeptember 11, 1 883.

App ication filed April 24,1883. x model.)

To all whom it may concern:

Be it known that I, MARTIN L1 BRAMHALLF of La Porte, La Porte county,and State of Indiana, have invented certain new and useful 5Improvements in'a feather-Strip, of which the following is a full,clear, and exact description, that will enable others to make and usethe same, reference being had to the accompanying drawings, and toletters of reference marked thereon, forming a part*of thisspecification.

This invention relates more especially to an improved weather-strip tobe used on doors, but may be so modified as to be applied to windows;and it consists of certain novel features in the construction andarrangement of Ehe parts, as will be hereinafter more fully set orth.

Figure 1 is an elevation of a door embodying my improved feature; Fig.2, a broken-away vertical transverse section of the lower end of thesame. Figs. 3, 4, and 6 are sectional details, showing:the constructionand arrangement of the mechanism connecting and controlling theadjustment of the weather-strip as the door is opened or closed. Fig. 5is aview of the plate set on the top of the weather-strip for theattachment of the inner end of the opcrating-levers.

Referring to the drawings, A A represents the door jambs or posts; A thedoor; A an ordinary knob-lock. The lower end of the door is providedwith a central rectangular recess, B, which receives the weather-strip.This recess is of some considerable depth and extends the whole width ofthe door, the bottom of the recess being of an irregular outline, asshown in Fig. 2 of the drawings.

The weather-strip consists of the wooden strip B and the rubber strip13", attached to the under side of the same. The upper side of the stripB is provided with the metal plates a a, which are duplicates of eachother, one of them being shown in Fig. 5. These plates are attached tostrip B by means of the screws a a and are provided with the elongatedapertures a, having the outer ends enlarged for p the insertion of thehead of the tap-bolt b, in-

serted in the under side and back end of the le- 50 vers O C. The stripB is provided with the elongated recess or recesses b, which correspondto the apertures in the plates a a, and allow the tap-bolt b to have amovement longitudinally therein. The levers C C are duplicates, the Iouter ends being formed with the bifurcated ends or arms d d (1 d asshown in Fig. 2 of the drawings. The ends of the lower; arms, d (1 areprovided with the pins b N, which have hearings in the staples b If,that pass through and rigidly secure the lower ends of the fiat 6osprings D D to the metal plates 0 0 attached to the front and back edgesof the door. The upper arms, d d, are secured to the thickened ends ofthe springs D D by means of the screwbolt 6 The inner end of thebeveledcatch D recessed into the front edge of the door, is attached to theouter side of the spring D by the screwbolt d, as shown in Fig. 6. Thecatch D does not engage with .a recess or become locked when the door isclosed, but performs the function of throwing the inner end of the leverO downward, imparting a corresponding move ment to the weather-strip.The catch D strikes against the curved plate (4 attached 7 5 to the jambA, which form causes a gradual downward movement of the weather-strip.

The upper outer side of the spring D, at tached tothe lever O, isprovided with the bolt F, which projects from the back edge of the doorwhen open, but is gradually forced inward by contact with the jamb whenthe door is closing. The springs D D serve to return the parts to theirnormal position when the door is opened, asshown in Fig. 2 of thedrawings, the dotted lines indicating the 0p posite position assumedwhen the door is closed.

The outer ends of the operating-levers, being something after the formof a bell-crank, havea somewhat similar action, the precise operationbeing as follows: As the door is being closed the bolt F at the backedge of the door is graduallyforced inward by frictional contact withthe jamb, which movement, through the medium of the lever O, firstthrows this end of the weather-strip down on the saddle of thethreshold, this being accomplished gradually as the door closes, and asthe catch, actuating the lever C at the front edgeof the door, in turncomes in contact with the curved strik- I00 ing-plate attached to thejamb, this end of the weather-strip is gradually moved down to a closebearing on the saddle. The tension of the springs D D may be regulatedby shortening or lengthening the bolts having frictional contact withthe door-j ambs. By this arrangement the weather-strip is automaticallyadjusted, is up out of the way and out of sight .when the door isopened, and contact with the saddle is so gradual that the wear isslight, and-it is not liable to get out of order or to be torn away.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-'- i 1. The combination, with the woodstrip B, supporting the elasticstrip B of the companion levers O G, theslotted plates 00 a, thesprings D D, the catch D the striking-plate (1.and

the projecting bolt F, all combined, arranged, and operatingsubstantially as set forth.

2. The combination, with the strip B, provided with the recess b 0f themetal plates a a, provided with the elongated apertures a, substantiallyas described.

3. The combination, with a weather-strip recessed in the under side of adoor, of the companion levers G O, the springs D D, the catch D, and thebolt F, whereby said weathcr-strip is automatically and graduallybrought in contact with the saddle of the threshold when the door isclosed and drawn up out of the way when the door is opened,substantially as and for the purpose set forth.
